SUN-RAY HEATER.

This invention relates to sun ray solar heaters and more particularly to a stationary form of this device employed in heating water.

An important object of the invention is to improve the structure of the heater as usually manufactured to render the same more efficient and rapid in its action.

A further object of the invention is to provide a device of this char acter which may be readily and cheaply produced and which will be durable and efficient These and other objects I in service. attain by the construction shown in the accompanying drawings,

wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure. 1 IS a plan view constructed in accordance tion, portions being broken away to the interior construction;

Figure 2 1s a sectlon on Figure 1.

of a solar heater with my lnvenshow the line 22 of Referring now more particularly to the drawing, the numeral 10 nates an open-topped box vided interiorly with generally desig- -like casing proinsulating lining 11.

Arranged interiorly of the lining uponthe bottom of the box are a plurahty of troughs 12 U-shaped in cross section,

from end to end of the each arranged thereina run 1 1 and 15 of which the ends of the casing.

the inlet and outlet ends are extended through Between adjacent walls of the which extend casing and have 13 of a pipe coil,

indicated at 17 of such depth that only the upper surfaces of the coil runs 13 are exposed. The upper ends of the arms or walls of the trough are as indicated at 18, thus pro offset outwardly, ducing at the upinsulating lining, a

this construction, the sun rays entering the container will be focused upon the pipe runs,

so that they will be subjected to an intense heat. The asphaltum surrounding the pipe, because of its heat absorbing qualities, tends to retain. the heat and prevent dispersal thereof before it has had a chance to act upon the fluid contents of the pipe.

-As the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not. limit myself to such specific structure except as hereinafter claimed.

I claim A solar topped box-like casing having an interior pipe coil arranged within the casing and including parallel runs, a trough receiving each run of the pipe coil, said troughs being U-shaped in cross section and having the upper ends of the arms thereof offset outwardly, the offset portions of the troughs abutting one another and a lens seated upon the shoulders formed by off-setting the arms of each trough and focused upon the run contained in the trough and heat insulating partitions between the troughs beneath the offset portions thereof. p

In testimony whereof I hereunto affix my signature.
